Abstract: 672,815. Awnings. LISLE, U. L. ORCHARD-. Nov. 27, 1950 [Nov. 25, 1949], No. 30324/49. Classes 20(i) and 20(iii) In an awning or tent top the material comprises a number of juxtaposed panels whose side edges lie in substantially the same plane, one end of each panel being wider than the other to form sloping troughs L1, L2 to permit rain water to run off. The fabric cover A of the awning is supported on parallel rods B, carried by vertical bars C connected by lazy tongs D, and is formed into a series of troughs L1, L2, alttrnate troughs sloping in' opposite directions, by means of seams H1, H2' formed along the centre line J1 of each panel lying between adiacent rods B. The seams H1, H2 have the effect of decreasing the width of each fabric panel at one end, so that the panel forms a sloping trough. In a modification, Fig. 2 (not shown), no seams are used, but the fabric is arranged so that the width of one end of each panel is greater than the other. The panels may, if desired, slope in the same direction, and again, each panel may be formed of a separate piece of material.

Title: Method of separation of acetylene and ethylene from a gaseous mixture and apparatus therefor
IPC: C07C7/11

Abstract: 950,971. Separating acetylene and ethylene from gases. KURASHIKI RAYON KABUSHIKI KAISHA. Aug. 23, 1961 [Oct. 14, 1960], No. 30388/61. Heading B1L. Acetylene and ethylene present in a gaseous mixture obtained by the decomposition of hydrocarbons are separated by first absorbing acetylene in a solvent therefor at 0-30 ‹C. and thereafter adsorbing ethylene at 0-30 ‹C. in a downwardly moving bed countercurrent adsorption separator. Absorbent liquids employed have boiling points above 100 ‹C. and dimethylformamide, γ-butyrolactone, dimethyl acetamide, N-methyl-pyrrolidone and dimethyl sulphoxide are specified. In Fig. 2 gases are produced e.g. from propane and steam or fuel gas, crude naphtha and oxygen in hydrocarbon decomposition apparatus A and after compression in compressor 1 are passed into absorbing tower 2, wherein acetylene is absorbed by a liquid in countercurrent flow, said liquid being supplied at the top of the tower from pump 23. Ethylene containing gases are removed via pipe 12 when acetylene has been absorbed to trace amounts. The liquid containing acetylene gas is pumped via 5 into a tower 3 having a heater 7 which drives off acetylene and the stripped absorbent is passed to cooler 6 and then recycled. The ethylenic gases pass through pipe 12 into adsorber 4 wherein said gases contact downwardly moving active carbon from which ethylene is released by means of heater 9 and is delivered via outlet pipe 20. Gas not adsorbed passes out via pipe 19. Active carbon is circulated by lift 10 and returns to the column via a cooler 8.

Abstract: Traces of gaseous hydrocarbons are removed from air by passage over cobalt oxide or cobalt and silver oxides, at temperatures from 80 DEG 180 DEG  C. and space velocities of 1,000-30,000 v/v/hr. The catalysts are prepared by precipitation from CO, or CO and Ag salt solutions by caustic soda or sodium carbonate, preferably in the presence of an oxidizing agent such as sodium hypochlorite or by passing air through the solution.  The precipitate is washed, formed into pellets and dried at 110 DEG  C.  The hydrocarbon oxidation is preferably effected at 5-300 atmospheres pressure and the treated air may then be passed to an air liquefaction plant without risk of explosion, preferably after removing the carbon dioxide oxidation product.

A wheel f is rigid with a shaft f<SP>1</SP> on which is secured a worm f<SP>2</SP> engaging a worm wheel a<SP>1</SP> rigid with a stationary liquid supply union i. A planet carrier g on which is journalled a planet pinion g' is rotatable about the shaft f<SP>1</SP>. and a pawl g<SP>2</SP> is pivoted on the planet carrier. A spring g<SP>3</SP> acts on the pawl to lock the planet pinion which causes the differential gearing and nozzle to turn, as a whole, about an axis XX'. An abutment h on a rod h' slidable in a sleeve h<SP>2</SP> engages a part g<SP>5</SP> of the pawl to cause disengagement of the pawl and planet pinion thereby enabling the pinion to rotate. Simultaneously the engagement of the parts g<SP>5</SP> and h prevents the planet carrier from turning so that the nozzle is turned in the opposite direction. Automatic reversal of the angular movement is obtained by manually adjustable rods j inserted into holes in a collar j' rigid with the union i. The rods are engaged alternately by a projection h<SP>3</SP> on the rod h' to effect longitudinal displacement of the rod and its abutment h.

A collet chuck comprises an externally tapered collet 17 which is internally threaded at its rear end to receive a driving sleeve 18. The sleeve has radial openings 20 housing a locking pin 21 which engages a flat 19 on the tool shank 8. The collet and sleeve are together inserted in a chuck body 1 having an internal taper which co-operates with the collet. A nose-piece 12 threadably engages the body 1 and retains the collet and sleeve therein. The screw action of the nose-piece also effects axial movement of the collet by way of the bevelled ring 9 and return ring 14 which effects in co-operation with the tapered surfaces, the gripping and releasing of the collet and sleeve on the tool shank. The shank is prevented from rotating and axial movement in the collet by the pin 21 and the flat 19. The axial position of the flat 19 is adjusted by screw 28 in the sleeve. An alternative embodiment has a tapered body only, which is radially split into three segments with springs between each. Axial adjustment of the tool shank in relation to the locking pin is effected by a screw in the chuck body.

The converter 12 drives a sun gear 17 while the converter 13 drives a sun gear 24 through a gear train 25 ... 27, the gears 17, 24 meshing with planet pinions on a carrier 19 driving a shaft 30 through a gear 29. The shaft 30 drives a pair of bevel gears 32, 33 either of which may be clutched to a wheel-driving shaft 34. Each engine is fitted with an all-speed governor 47, 48 connected to a single regulator 49. Fig. 4 shows a two-speed gear in which the shaft 30 is driven through a 2: 1 reduction gear 55, 56 from the planet carrier 19 until a metalto-metal friction clutch is engaged with a gear 29 to give a 1: 1 drive from the carrier to the shaft 30 and cause the drive from the gear 56 to be overridden by a unidirectional coupling 57. In an alternative construction, a double dog clutch connects the gears 29 and 56 alternately with the shaft 30. A fluid coupling may be used in place of the clutch 58. Each of the means 15, 16 consists of a helically splined sleeve 50 having a series of pawls 52a which run over a fixed set of dogs 53 until the drive is reversed when the pawls hold the sleeve stationary while the splines move it axially to bring dogs 52 into engagement with the dogs 53.
